` 1 9 claimsV (c1, 1-46)1 The invention aims to provide arather simpleand inexpensive, yet an efficient and reliable handfactuated machineYfor pinning "sheets of palper or sheets of other material together.

" 5 Abase is provided upon whichto rest the superposed sheets, a leverextends over this base 'and is mounted upon it, said lever beingprovided with Va pin hopper, a slide is employed to feed pins from thehopper to a pin receiver, co-acting "-19 means are provided onthe leverand base for imparting an arched formation to portions of the sheets,and provision is made for forcing a pin from the pinrec'eiver throughthe arched formation or crimp of the sheets.

'#16 Further objects are to provide novel construction to preventclogging ofthe pin outlet from vthe hopper; to provide novel meanspreventing movementof the pin forcing plunger into the pin v,receiveruntil the pin is properly 'positioned in "2b the latter; to preventreturn of the feed slide j to receive another pin, if the pin previouslypositioned in' the vpin receiver has not been forced from the latter;.and toprovide a novelrelation of lever fulcrum and slide pivot foroperating the 'e slide when the lever is operated. A

With the' foregoing in view, the invention resides in the novel subjectmatter hereinafter deseribedand claimed, description `being accomplishedby reference to the accompanying 'il 50 drawings.

AA substantially tend to the end of said leveropposite said handle 'slide zslsslidably received betweenthebottlhhorizontal lever 12 extends over the base 10 an'd is provided at one endwith an operating handle 13, said lever having two side arms 14 whichex- 13, said'side arms 14 having their edges presented upwardly andvdownwardly,L respectively. These arms 14 are `fulcrumed tothe upper endsofthe' posts 11 upon asuitable horizontal bolt or `the like 15, andappropriate spring means 16 is providedto normally swing the entirelever 12 upwardly to the position of Fig. 2. l

Fixedly mountedbetween the arms 14,-- is a pin hopper 17 having a pinoutlet slot 18 in itsbottom. Secured between the arms 14 under thishopper bottom and spaced` downwardly a slight distance therefrom, is apin receiver. 19 which is preferably in the 'form of a plateliaving 1Lgroove 20 spaced forwardly fromthe'slot 18 and opening upwardly. 'At theends of this groove 20, the sideumembers -14 of` the 1ever 12 are formedf5 with a plunger guiding-opening A21 adfagpin guiding opening 22, thelatter not only ektending through one of said side' membersbut openingthrough the lower edge thereof; V A pinfee'di'n'g of the hopper 17 andthepin receiver 1`9`,-`a.n`d the ,rear end of this slide ispivotedat24fbetween llower `ends ofthe postsjll, the pivotal axes of `thefulcrum 15 and the pivotv 24 being '1`3`a izl ll e l vertically spaced.B'y this relation of altes, when `85` the .lever 12 is depressed from(positionlof Fig 2 te that illustrated 1n Fig. afehe sle 23 will bermoved forwardly'. Thisslide is ,provided with a pin-receiving slot25and when this slot passes under the slot' 18, it receives a pin fromthe latter, slot 25 being only of a size to receive one pin at a time..`Theslot 25 moves the received for- Wardly and'drops it into the groove20,1and-wlin the lever 12 reachesthe limit of its'de'scent,.tl'ie pin'isforced from this groove throughthe super,- posed paper sheets, as willbe hereinafter n ioife fully explained. A hand-actuated plunger 2 '6 Visprovided to force the pin from the groove 20. Q-.In the present'showing, one end of this .plugeris carried by an appropriate slide27.engage`d with I00 a slotted guide arm 28 whichprojects laterally fromthe lever 12, theother end of saidy plunger ybeingreceived in theopening 21 as fslic "wn, il

Fig.` 4. By inwardly forcing uponthe 'slide 27, the plunger isprojectedlongitudinallythrough l`05 the groove 21 thereby driving thepin almost entirelythrough the opening22 as seen in Fig.

Any desired means may be employed for returning the plunger after'operation thereof. llor this purpose, I have illustrated Aaspring-:actuated arm 110 et j 29 pivoted at 30 to a lug 31 projectinglaterally from one of the side arms 14 of the lever 12.

Provision is made to prevent projection or" the plunger 26 into thegrove 20, until the lever 12 has been completely lowered and thepin istherefore in proper position for driving or forcing through the crimp ofthe superposed sheets. To perform this function, in the presentdisclosure, the slide 23 is provided with downwardly projectinglongitudinal vanges 321 received in notches 33 inthe upper-side of thepin-receiving plate 19, .one of said flanges acting as a gate andnormallyclosing the-groove 20 against entrance of the plunger 26.lowered however, the flanges move forwardly `from the groove as seen inFig. 3, therebyrallowing operation of the plunger 26.

Further provision is made Ato prevent return ofthe plunger 23 to receiveanother pin, if the pin previously positioned in the groove 20`has notbeen driven. In the present showing, this func- .tion'is performed by alug 34 projecting downwardly fromV the slide23 into a'grocve 35 in theupper'side of the pin-receiving plate 19. When theparts are at rest andgroove 20 is empty as seen in Fig. 2, 'the lug 34 is behind the grooveas illustrated in this view. As the machine is operatedv and the slide23 moves forwardly to position a pin in the grove 20, the lug 34 movesacross said groove priorto such pin positioning. Thus,

'when the pin drops into the groove fromthe slide, the lug 34 is inadvance of this pin, as seen vin Fig. 3.' Consequently, the lug 34 willstrike the pinv and lock the slide and the lever against return ytonormal position until said pin has been driven.

vThe pin 'outlet slot 18 in the hopper 17 is preferablyndisposed' in thelower front corner of the latteryand thefront wall of the latter isprovided. with a portion 36V which overhangs said slot, lprovidingraninwardly opening groove 37 into which one or more of the pins must enteribefore oneof themcan drop into said slot 18.

Spaced lugs 38 are provided on the upper side l,of the'jslide23,"movable vinto and from slots 39 in fthe hopper 17, to push a numberof the pins genjtlyftowardthegroove 37, Awhen said slide 23 movesforwardlywith respect to said hopper, thereby rearwardly v`withfrespecttothe hopper. "By providing" the 'overhanging wall portion 36,.

the groover ,37,l the lugs 38 and the lugs 40, only a few of ythe pinscan gather over the'slot 18 and thereris -little likelihood of anyof thepins be- 'cming'jdi'sarranged or stickingk and. failing to enterfsaidslot 18.' Moreoven'itris insured 4that Veven if there' be only one pinin the groove 37, 'it

,shall enter Ythe, slot 18.

Secured upon the base 10, is a longitudinal rib 42Y having an upwardlyopen groove 43 which is alined with the groove 20 andtheV openings 21and 272, when thelever 12`is`depressed, as .seen linFigs. 'I4 and 5.Portions of the superposed .sheetsvare laid upon this, rib beforedepressing the lever 12, and one'of the side members 14 of the llatteris provided with an appropriately shaped ange 44 which co-operates withsaid rib in formingthe sheets with arched formations 45, through whichthe pin 46 is driven upon operation of the plunger 26. `A portion47 ofone of the lever side members 14 also assists in impart- By the timelever 12 has been completely' ing the arched formation to the sheets.The lever portion 44 is of course formed with a suitable notch 48 whichclears the pin 46 when the lever 12 is again raised after completionfofthe pinning operation.

A longitudinal nger 49 is secured at one end upon the base 10, thegreater part of said finger being spaced above said base and servingtosupport one vor vmoreof the upper sheets above the remainder of saidsheets, vaswill be clear from Figs. 4 and 5', it being of courseunderstoodthat mostof the sheets are inserted under this finger before.being placed over the rib 42, whereas the produces a channel formation50 in the sheet or sheets passing over the finger 49. When the pin 46 isdriven, it passes through both the arched and the channel formations ofthe sheets so that the pointed end ofthe pin is' received between thelower and the upper sheets, as illustrated 4in Fig', 5.Y c Thus, whenthe sheets are removed from the machine, the pin point is sojpositionedhandling the pinned sheets and no'danger of it catching into apparel,vor any other articles into contact with which the pinned sheets may bemoved.

der to pin a plurality of sheets together, it is simplyl necessary vtoplace the latter upon theV rib 42, placing an upper sheet or sheets overthe nger 49, depress the lever handlek 13,'until the parts reach thelimit of their downward movement, and then inwardly push upon theplunger 26. When this plunger is released, it automatically returns toretracted position andvwhen the lever handle 13 is released, the spring16' restores the sitions, in readiness for further use. The opening 22and notch 48 clearl the driven pin as the lever 12 returns toits normalraisedposition.
